Optimally, perhaps, but as fast as some cameras are - they can rip
off three shots fast enough to not matter. The new Sony SLR based
on Minolta technology can rip off shots at 5 FPS at it's full 12+ Mp
resolution -- that three shots (bracketed) in .6 seconds... And with the
camera's "anti-shake" systems - the field won't move (the subject might
- but a tripod won't help in that case either).

Correct. But you still want the aperture to be the same. If you're
bracketing +/- two stops (which would be normal for capturing a wide
brightness range) and the camera is set for Program, the aperture might
change.
